Since the diagram is not provided, let’s describe molecule movement along the cell membrane generally. Molecules may passively travel through the cell without energy, an example being oxygen molecules. However, larger and non-polar molecules struggle to cross the membrane easily. These particular molecules will need energy to be transported through the membrane and may do so with the aid of carrier or facilitated proteins, such as glucose molecules.
Answer:
Ethylene. (Ans. D)
Explanation:
Ethylene controls the aging and ripening processes in plants. While many fruits and vegetables generate small amounts of ethylene, climacteric fruits like bananas produce larger quantities. This ethylene release accelerates respiration, triggers more ethylene production, and causes changes in color and flavor.
Therefore, when transporting green bananas over long distances to stores, the ethylene gas should be removed from their surrounding environment.
During step 3, chromosomes switch genetic information.
Clarification:
Meiosis is a form of cell division occurring in gamete formation. This process consists of two main stages - meiosis I and meiosis II.
Within meiosis I, events such as crossing over and independent assortment occur, leading to the exchange of genetic traits between pairs of homologous chromosomes and the division of these chromosome pairs. Therefore, the two cells generated from meiosis I will be genetically distinct. Step 3 illustrates the crossing over that happens during prophase 1 of meiosis I. Consequently, this results in genetic variation among offspring.
FAT soluble nutrients enter the lymphatic system after absorption, while WATER soluble nutrients enter the portal circulation. Once absorption takes place in the body, the large fat-soluble nutrients are initially absorbed into the lymphatic system before being transported into the bloodstream, whereas water-soluble nutrients travel through the hepatic portal veins to reach the liver.
